Published by Institute of Electrical and Electronics Engineers Inc 2 DESCRIPTION This manual covers the operation of the DSE Configuration Suite for the DSE7450 module. Separate manuals cover the remaining DSE modules supported by the software. The DSE Configuration Suite allows the DSE7450 module to be connected to a PC via USB A USB B cable. Once connected the various operating parameters within the module is viewed or edited as required by the engineer. This software allows easy controlled access to these values and also has diagnostic monitoring facilities. The configuration suite should only be used by competent, qualified personnel, as changes to the operation of the module may have safety implications on the panel / generating set to which it is fitted. Access to critical operational sequences and settings for use by qualified engineers, may be barred by a security code set by the generator provider. The information contained in this manual should be read in conjunction with the information contained in the appropriate module documentation. This manual only details which settings are available and how they may be used. A separate manual deals with the operation of the individual module (See section entitled Bibliography elsewhere in this document). 3 INSTALLATION AND USING THE DSE CONFIGURATION SUITE SOFTWARE For information in regards to instating and using the DSE Configuration Suite Software please refer to DSE publication: DSE Configuration Suite PC Software Installation & Operation Manual which is found on our website: 6

Click OK to accept the changes and return to the configuration editor Click OK to save the curve. Any saved curves become selectable in the Input Type selection list. Hint: Deleting, renaming or editing custom sensor curves that have been added is performed in the main menu, select Tools Curve Manager.. 21

22 Edit Configuration - Inputs DIGITAL INPUTS The digital inputs page is subdivided into smaller sections. Select the required section with the mouse. Input function. See section entitled Input functions for details of all available functions Configures when the input is active: Never, always, active from starting, active from the end of the safety timer This is the text that will be displayed on the module screen when the alarm is triggered. Click and drag to change the setting. This is used to give a delay on acceptance of the input. Useful for liquid level switches or to mask short term operations of the external switch device. As this example shows a predefined function, these parameters are greyed out as they are not applicable Example of a user configured input Close or open to activate Select the type of alarm required. For details of these, see the section entitled Alarm Types elsewhere in this document. 22

23 Edit Configuration - Inputs DIGITAL INPUT FUNCTIONS Where a digital input is NOT configured as user configured, a selection is made from a list of predefined functions. The selections are as follows: Under the scope of IEEE 37.2, function numbers are also used to represent functions in microprocessor devices and software programs. Where the DSE input functions are represented by IEEE 37.2, the function number is listed below. NOTE: Input selection is dependant on controller. Function Air flap closed auxiliary IEEE Checking or interlocking relay Alarm Mute Alarm Reset Alt Config 1-3 Select Alternative Language Select Auto Restore Inhibit IEEE checking or interlocking relay Auto start Inhibit IEEE checking or interlocking relay Auxiliary Mains Fail Description This input is used to connect to the Air flap switch contacts. This gives an immediate shutdown in the event of the air-flap being closed. It also prevents the generator from being restarted if the air flap has not been reset following an overspeed shutdown. This input is used to silence the audible alarm from an external source, such as a remote mute switch. This input is used to reset any latched alarms from a remote location. It is also used to clear any latched warnings which may have occurred (if configured) without having to stop the generator. These inputs are used to instruct the module to follow one of the alternative configuration settings instead of the main configuration settings. This input is used to select the alternative uploaded language file. In the event of a remote start/mains failure, the generator is instructed to start and take load. On removal of the remote start signal/mains return the module continues to run the generator on load until the Auto Restore Inhibit input is removed. This input allows the controller to be fitted as part of a system where the restoration to mains is controlled remotely or by an automated system. This input is used to provide an over-ride function to prevent the controller from starting the generator in the event of a remote start/mains out of limits condition occurring. If this input is active and a remote start signal/mains failure occurs the module doesn't give a start command to the generator. If this input signal is then removed, the controller operates as if a remote start/mains failure has occurred, starting and loading the generator. This function is used to give an AND function so that a generator is only called to start if the mains fails and another condition exists which requires the generator to run. If the Auto start Inhibit signal becomes active once more it ignores until the module has returned the mains supply on load and shutdown. This input does not prevent starting of the engine in MANUAL or TEST modes. The module monitors the incoming single or three phase supply for Over voltage, Under Voltage, Over Frequency or Under frequency. It may be required to monitor a different mains supply or some aspect of the incoming mains not monitored by the controller. If the devices providing this additional monitoring are connected to operate this input, the controller is operated as if the incoming mains supply has fallen outside of limits, the generator is instructed to start and take the load. Removal of the input signal causes the module to act if the mains has returned to within limits providing that the mains sensing also indicates that the mains is within limits. 23

24 Edit Configuration - Inputs Function Coolant Temperature Switch Crank Disconnect Disable Protections Droop enable EJP1 EJP2 Description This input is used to give a Coolant Temperature High shutdown from a digital normally open or closed switch. It allows coolant temperature protection using the switch and the analogue input is used to give protection or configured to be used for indication only. This input is used to give an external crank disconnect input. The system designer provides this switch (not DSE) so its location varies depending upon manufacturer, however it normally takes the form of a key operated switch to prevent inadvertent activation. Depending upon configuration, a warning alarm may be generated when the switch is operated. When active, and the module is suitably configured (see section entitled Application ) this prevents the engine being stopped upon critical alarm (Sometimes called War Mode or Run to Destruction) This input is used to switch the engine into droop mode on CAN engines that support this function. For the French EJP (Effacement Jours de Pointe) tarrif system. This input is functionally identical to Remote Start Off Load. If this input is active, operation is similar to the Remote Start on load function except that the generator is not instructed to take the load. This function is used where an engine only run is required e.g. for exercise. For the French EJP (Effacement Jours de Pointe) tarrif system. This input is functionally identical to Remote Start On Load. External Panel Lock When in auto mode, the module performs the start sequence and transfer load to the generator. In Manual mode, the load is transferred to the generator if the engine is already running, however in manual mode, this input doesn't generate start/stop requests of the engine. In both cases, synchronising takes place if required. This input is used to provide security to the installation. If the External Panel lock input is active, the module doesn't respond to operation of the Mode select or start buttons. This allows the module to be placed into a specific mode (such as Auto) and then secured. The operation of the module is not affected and the operator is still able to view the various instrumentation pages etc. (Front panel configuration access is still possible while the system lock is active). NOTE: External control sources (i.e. Simulate Start Button) are not affected by the external panel lock input and continue to operate normally. Fuel Pump Control Fuel Usage Alarm This input is used to activate the fuel Pump output control. When active the Fuel control output is active When inactive Fuel control output is not active. This Input is used to give an input from an external fuel usage alarm. 24

25 Edit Configuration - Inputs Function Generator Closed Auxiliary IEEE Checking or interlocking relay Generator Load Inhibit IEEE AC circuit breaker Description This input is used to provide feedback to allow the DSE7450 to give true indication of the contactor or circuit breaker switching status. It should be connected to the generator load switching device auxiliary contact. Action: Warning (Alarm only, No shutdown) This input is used to prevent the controller from loading the generator. If the generator is already on load, activating this input causes the controller to unload the generator. Removing the input allows the generator to be loaded again. NOTE: This input only operates to control the generatorswitching device if the DSE7450 load switching logic is attempting to load the generator. It doesn't control the generator-switching device when the mains supply is on load. Generator Loading Frequency OK Generator loading Voltage OK High Coolant Temperature Electrical Trip Inhibit Retransfer To Mains IEEE checking or interlocking relay Inhibit Scheduled Run IEEE checking or interlocking relay Inhibit SMS Remote Start Lamp Test Low Fuel Level Switch Main Config Select Mains closed Auxiliary IEEE Checking or interlocking relay Mains Fail This input is used when the loading Frequency is within acceptable limits before allowing the generator to go on load when active This input is used when the loading Voltage is within acceptable limits before allowing the generator to go on load when active This Input is used to Electrically trip the Generator breaker upon an external high coolant temperature sensor becoming active. When active, this input prevents the load being transferred back to the mains supply, even in the event of the generators failing. This input is used to provide a means of disabling a scheduled run. This input is used to provide a means of disabling SMS Remote Start. This input is used to provide a test facility for the front panel indicators fitted to the DSE module. When the input is activated all LED s should illuminate. A digital normally open or closed fuel level switch gives this input. It allows fuel level detection using the switch and the analogue input to be used in parallel to give protection or to be used for fuel level indication only. This input is used to select the Main configuration when Alternative configurations are enabled. This input is used to provide feedback to allow the module to give true indication of the contactor or circuit breaker switching status. It should be connected to the mains load switching device auxiliary contact. Incorrect application of this signal does not trigger an alarm condition, it is used solely for indication of the breaker status. This input is used to give indication to the module of a mains failure while the input is active. 25

26 Edit Configuration - Inputs Function Mains Load Inhibit IEEE checking or interlocking relay Description This input is used to prevent the from loading the mains supply. If the mains supply is already on load activating this input causes the module to unload the mains supply. Removing the input allows the mains to be loaded again. NOTE: This input only operates to control the mains switching device if the DSE7450 load switching logic is attempting to load the mains. It does not control the mains switching device when the generator is on load. Manual Restore Contact Oil Pressure Switch Remote Start off load Remote Start on load Reset DC Battery Reset DC Battery Maintenance Alarm 1-3 Reset Maintenance Alarm 1-3 Simulate Auto Button In the event of a remote start/mains failure, the generator is instructed to start and take load. A digital normally open or closed oil pressure switch gives this input. It allows oil pressure protection using the switch and the analogue input to be used in parallel to give protection or to be used for oil pressure indication only. If this input is active, operation is similar to the Remote Start on load function except that the generator is not instructed to take the load. This function is used where an engine only run is required e.g. for exercise. When in auto mode, the module performs the start sequence and transfer load to the generator. In Manual mode, the load is transferred to the generator if the engine is already running, however in manual mode; this input does not generate start/stop requests of the engine. This input is used to indicate a new plant battery has been installed, by activating this input the Plant Battery Status instruments reset all to zero (Battery Run Time, Battery Charge Cycles, Battery Discharge %, Battery Charge %, Battery Power %), the Plant Battery Manitenance Alarms (1,2,3) and DOD Alarms are reset as well. These inputs are used to reset the DC Battery maintenance alarms. When activated it resets the maintenance counter to the pre-configured value (i.e. 250 hours). If the maintenance alarm is configured to monitor the monthly service interval this also resets to the pre-configured period (i.e. 6 Months). These inputs are used to reset the maintenance alarms. When activated it resets the maintenance counter to the pre-configured value (i.e. 250 hours). If the maintenance alarm is configured to monitor the monthly service interval this also resets to the preconfigured period (i.e. 6 Months). NOTE: If a call to start is present when AUTO MODE is entered, the starting sequence begins. Call to Start comes from a number of sources depending upon module type and configuration and includes (but is not limited to) : Remote start input present, Mains failure, Scheduled run, Auxiliary mains failure input present, Telemetry start signal from remote locations. This input mimic s the operation of the Auto button and is used to provide a remotely located Auto mode push button. 26

27 Edit Configuration - Inputs Function Simulate Lamp test \ Alarm Mute Button Simulate Mains available Simulate Manual Button Simulate Start Button Simulate Stop Button Simulate Test on load button Smoke Limiting IEEE accelerating or decelerating device Start Pause IEEE checking or interlocking relay Stop and Panel Lock Transfer to Mains/ Open Generator / Battery Button IEEE AC circuit breaker Transfer to Generator/Open Mains / Battery Button IEEE AC circuit breaker Description This input is used to provide a test facility for the front panel indicators fitted to the module. When the input is activated all LED s should illuminate. The input also serves a second function, in that it also provides a mute signal to silence the audible alarm. The input is recognised by the module as though it was the Push button on the module itself being operated. This function is provided to override the module s internal monitoring function. If this input is active, the module does not respond to the state of the incoming AC mains supply. This input mimic s the operation of the Manual button and is used to provide a remotely located Manual mode push button. This input mimic s the operation of the Start button and is used to provide a remotely located start push button. This input mimic s the operation of the Stop button and is used to provide a remotely located stop/reset push button. This input mimics the operation of the Test button and is used to provide a remotely located Test on load mode push button. This input instructs the module to give a run at idle speed command to the engine either via an output configured to smoke limit or by data commands when used with supported electronic engines. This input is intended to be used to allow the generator start sequence to commence, but not to complete. This feature is used with Air start engines for example to give a controlled start sequence. The function operates such that if the Start pause input is active and an engine start is commanded, the module performs its start sequence thus: The pre-heat output (if used) is activated for the duration of the pre-heat timer. The Fuel output is then energised and the module then enters a pause state - Awaiting clear to start. If the start pause signal becomes inactive at this time then the module continues its normal start sequence. The start pause mode uses the manual crank limit timer and if this expires during the Awaiting clear to start state then a Fail to start alarm is generated and the set shutdown. Combined function input that instructs the module to enter STOP MODE and also perform the Panel Lock function. Once the input is active, the module does not respond to operation of the Mode select or start buttons. The operator is still able to view the various instrumentation pages etc. (Front panel configuration access is still possible while the system lock is active). This input is used to transfer the load to the mains supply (AMF module) when running in MANUAL MODE or provide the Open Generator signal in a non AMF Module.) This input is used to transfer the load to the generator when running in MANUAL MODE.. 27

28 Edit Configuration - Inputs Function Volts Lower Volts Raise Description NOTE: This input has no effect when using the internal analogue system to control the AVR This is operational in Manual Mode only, when the breaker is open. On systems where internal relays are used to control the AVR, this input is used to decrease the volts. NOTE: This input has no effect when using the internal analogue to control the governor.

Timers not associated with an alarm are located on the timers page. The Timers page is subdivided into smaller sections. Select the required section with the mouse START TIMERS Click and drag to change the setting. Timers increment in steps of 1 second up to one minute, then in steps of 30 seconds up to 30 minutes, then in steps of 30 minutes thereafter (where allowed by the limits of the timer). Timer Remote Start Off Load Remote Start On Load Mains fail Telemetry Start Description Used to give a delay before starting in AUTO mode. This timer is activated upon the respective start command being issued. Typically this timer is applied to prevent starting upon fleeting remote start signals or short term mains failures. Parameters detailed overleaf... 42

43 Edit Configuration - Timers Timer Pre-heat Pre-heat bypass Cranking time Crank rest time Engage Attempt time Engage Rest Time Delay Crank Smoke limit Smoke limit off Safety on delay Warming up time Sensor fail delay Description Give a pre start time during which the Preheat output and Starting alarm becomes active (if configured) Should the set be stopped, the Pre-heat bypass timer begins. Should the set be called to start again, before the timer expires, the pre-heat sequence is bypassed as heating is not required since the set is still warm after the last run. The length of each crank attempt The time between multiple crank attempts. (Only available if using Magnetic pick-up and multiple engage attempts) This timer dictates the duration that the module attempts to engage the starter motor during each engage attempt. If the Magnetic Pick-up is not detecting movement of the flywheel when this timer expires, the engage attempt terminates. Once all engage attempts have been made, the next start attempt begins. (Only available if using Magnetic pick-up and multiple engage attempts) This timer dictates the duration that the module waits between attempts to engage to starter. This is the difference in time when the fuel relay energises and the crank relay energises. The amount of time that the engine is requested to run at idle speed upon starting. This is typically used to limit emissions at start up. This should be set to a little longer than the amount of time that the set takes to run up to rated speed after removal of the command to run at idle speed. If this time is too short, the set could be stopped due to under speed failure. If the time is too long, under speed protection is disabled until the Smoke limit time off time has expired. The amount of time at start up that the controller ignores oil pressure, engine speed, alternator voltage and other delayed alarms. This is used to allow the engine to run up to speed before protections are activated. The amount of time that the set runs BEFORE being allowed to take load. This is used to warm the engine to prevent excessive wear. (Only available if using Magnetic pick-up) This is only used if magnetic pick speed sensing is selected. Once cranking has commenced the module must receive a speed signal within this time. If no signal is present, the engine stops and a Loss of Speed Sensing alarm given. 43

Timers increment in steps of 1second up to one minute, then in steps of 30 seconds up to 30 minutes, then in steps of 30 minutes thereafter (where allowed by the limits of the timer). Timer Transfer time/ Load Delay Breaker close pulse Breaker Trip pulse Return delay Cooling time ETS Solenoid hold Fail to stop delay Generator transient delay Description This timer has two functions 1: The time between the mains load switch being opened and the generator load switch being closed (and vice versa). 2. The time between the Load Shed Control outputs (if configured) being energised and the generator being placed on load (at start up). The amount of time that Breaker Close Pulse signals is present when the request to close a breaker is given. The amount of time that Breaker Open Pulse signals is present when the request to open a breaker is given. A delay, used in auto mode only, that allows for short term removal of the request to stop the set before action is taken. This is usually used to ensure the set remains on load before accepting that the start request has been removed. The amount of time that the set is made to run OFF LOAD before being stopped. This is to allow the set to cool down and is particularly important for engines with turbo chargers. The amount of time the Energise to stop solenoid is kept energised after the engine has come to rest. This is used to ensure the set has fully stopped before removal of the stop solenoid control signal. If the set is called to stop and is still running after the fail to stop delay, a Fail to Stop alarm is generated. Used to delay the generator under/over volts/frequency alarms. Typically this is used to prevent spurious shutdown alarms caused by large changes in load levels. 44

87 Edit Configuration - Communications TROUBLESHOOTING MODEM COMMUNICATIONS MODEM COMMUNICATION SPEED SETTING First ensure the modem is set to communication with the DSE module at 9600 baud Modems supplied by DSE are factory adjusted to operate with the module. Only modems purchased from a third party may require adjustment. To change the modems RS232 baud rate a command line terminal program (Hyperterminal by Microsoft is a good solution) is needed. Operation of this terminal program is not supported by DSE; you should contact your terminal program supplier. Connect the modem RS232 port to your PCs RS232 port. You may need an additional card in your PC to provide this facility. Use Hyperterminal (or similar) to connect to the modem at its current baud rate. You may need to contact your modem supplier to obtain this detail. If this is not possible, use trial and error methods. Select a baud rate, attempt connection, press <ENTER> a few times. If the modem responds with OK> then you are connected at the correct baud rate. Any other response (including nothing) means you are not connected so select another baud rate. When connected, enter the following command: AT+IPR=9600 and press <ENTER> This sets the modem to 9600 baud. Close the Hyperterminal connection (do not remove power from the modem) then open a new connection to the modem at 9600 baud. Enter the following command: AT&W and press <ENTER> This saves the new setting in the modem. Power is now removed. The next time power is applied, the modem starts with the new settings (Baud rate = 9600), suitable to communicate with the DSE module GSM MODEM CONNECTION Most GSM modems have a Status LED. The Wavecom Fastrack Supreme as recommended and supplied by DSE has a RED Status LED, operating as follows. LED STATE Off On Continuous Flashing Slow (approx once every two seconds) Flashing Fast (approx twice per second) Description Modem is not powered Not connected to GSM network Connected to GSM network Connected to GSM network data transmission in progress. 87

88 Edit Configuration - Communications RS485 PORT Modbus Slave ID Baud rate adjustable from Timer Master inactivity timeout Description The module looks by default at the USB port for communications. When activity is detected on the RS232 or RS485 port, the module switches to look at the relevant port for further data. If no data activity is detected on the port for the duration of the master inactivity timer, it reverts to looking at the USB port. This should be set longer than the time between modbus polls from the master. 88

89 Edit Configuration - Communications ETHERNET PORT NOTE: Consult the network administrator of the host network before changing these settings. Incorrect settings could cause network errors in the existing network. These settings must only be changed by qualified network administrators. After the IP address is changed by writing the configuration, the controller must be power cycled before the change takes effect. Network port number that the modbus TCP communications will operate over. Ensure any firewall in the system (for instance within the router) is configured to allow traffic on this port. Firewall configuration for internet access As modem/routers differ enormously in their configuration, it is not possible for DSE to give a complete guide to their use with the module. However it is possible to give a description of the requirements in generic terms. For details of how to achieve the connection to your modem/router you are referred to the supplier of your modem/router equipment. The module makes its data available to a configurable TCP port number. You must configure your modem/router to allow inbound traffic on this port. For more information you are referred to your WAN interface device (modem/router) manufacturer. Incoming traffic (virtual server) Network Address and Port Translation (NAPT) allows a single device, such as the modem/router gateway, to act as an agent between the Internet (or "public external network") and a local (or "internal private") network. This means that only a single, unique IP address is required to represent an entire group of computers. For our application, this means that the WAN IP address of the modem/router is the IP address we need to access the site from an external (internet) location. When requests reach the modem/router, we want this passed to a virtual server for handling. 89

90 Edit Configuration - Communications Example Virtual Servers Filter Name Port Destination (LAN) Address DSE IP Address of the Controller User provided name for the Port Forwarding rule Port number of the communications (must match the configuration of the controller Result : Traffic arriving from the WAN (internet) on port 1003 is automatically sent to IP address on the LAN for handling. 90

When protections are disabled, Protections Disabled appear on the module display to inform the operator of this status. 106

107 Edit Configuration Advanced PLC LOGIC PLC Logic adds comprehensivee PLC functionality to the DSE controller. This is an advanced section, used entirely at your own risk MENU PLC Logic Conditions PLC Logic Actions PLC Logic Counters & Timers configuration, copy, folder and search options In PLC logic, the ladder of logic is made up of a series of rungs. The ladder is the complete PLC program. This program may perform a single task, or multiple tasks. Each rung contains a number of conditions and actions. For instance if the conditions in the rung are met, the action takes place. Condition (example Check Flag) Action (example Start timer) PLC Ladder made of two rungs Click the to erase the entire rung A condition with a diagonal line through it means NOT. (example Timer has NOT expired) 107

108 Edit Configuration Advanced FLAGS A flag is set when a condition within the DSE controller is met. For instance, if the module is in Auto Mode an internal flag is set. This flag is exposed as an output source when configuring module outputs and LEDs. In addition to internal flags, a further twenty (40) custom flags are available (named PLC Output Flag 1-40). These are used to memorise that a condition has been met, and/or used to drive module outputs and LEDs. For example if a timer expires, a flag is set to make a note of the timer expiring for later use in the ladder TIMERS The PLC logic section contains twenty (20) user timers for use in the ladder. A timer is configured by clicking in the menu bar. The Edit time limits window appears. Click and drag to change the time, or press keyboard left and right arrow keys to change by small amounts. A timer is used by adding the timer action to the ladder. When this action takes place, the timer begins. Upon the timer reaching the configured Timer limit, a test for the timer is successful: Start Timer Test Timer 108

109 Edit Configuration Advanced COUNTERS The PLC logic section contains twenty (20) user counters for use in the ladder. A counter is configured by clicking in the menu bar. The Edit counter limits window appears. Click and drag to change the setting, or press keyboard left and right arrow keys to change by small amounts. A counter is used by incrementing (adding to) or decrementing (subtracting from) to the counter on the ladder. Upon the counter reaching the configured Counter limit, a test for the counter is successful: Increment Counter Decrement Counter Test Counter 109

110 Edit Configuration Advanced PLC FUNCTIONS PLC Functions allow the PLC logic to create alarm conditions or drive virtual inputs on the controller. A PLC function is configured in the same way as a module digital input: Predefined Functions Function. See section entitled Input functions for details of all available functions As this example shows a predefined function, these parameters are Predefined functions are only used once in the DSE Configuration Suite. For example if digital input A is configured to remote start on load, another input cannot be configured to the same function. Similarly, a PLC function cannot be configured to this function either. Where this is a required function, it is achieved by setting the digital input to User Configured, always active, indication, and OR ing this into the PLC condition as follows: Condition: Battery Volts below 10V OR Digital input A is active. Action: Trigger PLC Function 1(Remote Start On Load) 110

111 Edit Configuration Advanced User Defined alarms Configures when the input is active: Never, always, active from starting, active from the end of the safety timer This is the text that will be displayed on the module screen when the alarm is triggered. Example of a user configured input Close or open to activate Select the type of alarm required. For details of these, see the section entitled Alarm Types elsewhere in this document. Click and drag to change the setting. This is used to give a delay on acceptance of the input. Useful for liquid level switches or to mask short term operations of the external switch device. 111

112 Edit Configuration Advanced CREATING AND EDITING RUNGS Click a symbol in the tool bar and drag it to the bar ( ) to create the first rung in your ladder. Click a symbol in the tool bar and drag it to a blank space below existing rungs to create a new rung. Click a symbol in the tool bar and drag it to the ladder diagram to place the symbol. To move a placed symbol, click and drag it to its new location. To copy a placed symbol, press the keyboard CTRL button, then click and drag the symbol to the location you want to copy it to. To delete a placed symbol, click on it, it changes colour to red, now press the keyboard DELETE button. Click next to a rung to erase the entire rung. Imagine the schematic like a simple circuit with a battery and a bulb. There are two switches (Output sources) in parallel to provide an OR function and one switch (Output source) in series to provide an AND function. When the conditions are satisfied, the bulb illuminates (The action occurs). An equivalent PLC ladder rung looks like this : Rungs are processed in order (rung 1, rung 2, rung 3 etc). This sequence repeats every 100mS. Careless setting of the PLC logic causes toggling of an output at a rate of 100mS on/off. This may shorten the life and/or cause damage to externally connected slave relays or other connected equipment. Conditions are placed in seriess to form an AND operation, or in parallel for form an OR operation: PLC Logic OR Conditions PLC Logic AND Conditions Actions are placed in parallel to perform multiple actions upon one condition: PLC Logic multiple actions 112
